IMPRQVEMENT IN GRAI N-SEPARATORS.

To all whom, it may concern:

Be it known that I, MYnoN J. BAucALo, of Mount Morris, in the county of Livingston and State of New York, have invented a new and useful Improvement in Grain-Separating Apparatus and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings and the letters marked thereon, making a part of this specification, in which- Figure 1 is a perspective view of the shoe, a portion of one side being broken away to show the arrangement of the sieve and separator. Fig. 2 is a vertical longitudinal section of sieve and separator. Figs. 3, 4, and 5 show different methods of constructing the separator. Fig. 6 shows the common mode of adiustin g the separator vertically.

My invention consists in the peculiar construction and application of the separator whereby a more thorough cleaning of the grain is effected than can be attained by the means commonly used.

To enable others to make and use my invention, I will proceed to describe its construction and operation.

I construct the sieve A in any ordinary or suitable manner, but preferably in the manner secured to me by Letters Patent dated June 23, 1863. ()n the under side of the lower or rear end of the frame of the sieve I attach the trapezoid B. At the bottom edge of B, I attach the separator O, which is constructed as follows: The frame extends across the whole width of the sieve and about six or eight inches of its length, though this latter dimension is not absolute, but may be varied as desired. It may be made so as to present a flat surface, as in Fig. 2, but preferably with a slightly-arched surface, as shown in Figs. 3, 4, and 5. This frame I cover with wire-gauze, the front edge of which, 0', is slightly bent up ward, in order to prevent any grain cast upon the separator from falling over that end. It may also be covered at the edge c with a plate of metal, D, which will either entirely cover the edge of the wire-gauze, as seen in Figs. 2 and. 5, or leave the turned-up edge of the wire gauze exposed, as in Fig. 3. The separator is attached to the trapezoid B by means of the screws E,which are inserted through the slots 6 in the frame 0, as shown in Fig. 4, which arran gement allows the separator to be adjusted longitudinally. The separator may also be adjusted to a greater or less inclination to the sieve A by loosening the screws E and insertin g small wedges either under the front or rear end, as may be desired, as seen in Fig.6. The sieve A is adjusted vertically and maintained in position by means of a thumbserew or any other suitable device.

In order to operate my apparatus in the most efficient manner, it is necessary to adjust the discharging screen F by sliding it forward in its gains; but, as in many mills it is impossible to do this without the projected end of the screen F becoming an obstruction to the blast, it is often necessary to use a shorter discharging-semen.

The operation of my machine is as follows: The sieve and separator, being ready for use, are placed in the shoe G, the front end of the sieve being supported by the ends of the adjustable strips H, which project a short distance from the edge of the sieve for that purpose, or it may be supported by any other convenient device. The sieve is adjusted to the proper inclination and secured in position bya set-screw, s, or other suitable method. The mill now being set running, the grain descending from the hopper upon the chute I is, by the vibration of the shoe, carried down over the sieve A, where in practice it is found that the heavier kernels settle to the surface of the sieve,and consequently first pass through the meshes, while the lighter kernels and grains of less gravity-as oats, &c. -are passed farther down the sieve.

The separator is so adjusted by sliding it longitudinally in the slots 0 of the frame 0 as to catch all these lighter grains upon its surface, where they are a second time screened and separated, and thus the wheat will be kept distinct and apart from the oats, which are passed over the lower end of the screen outside of the machine.

A further and more complete separation of the lighter from the heavier wheat is often desirable in obtaining seed-grain, and this may be accomplished by such an adjustment of the discharging-screen F in its gains, as shown by red arrow, that none but the heaviest and soundest grains will be caught upon its surfacc-that is to say, those which pass through the meshes of the sieve nearest to its upper end, while all the rest of the wheat will fall past the discharging-screen into a receptacle separate and apart.

What I claim as my invention, and desire to secure by. Letters Patent, is

1. The longitudinally and vertically adjustable separator O, constructed of wire-gauze,or partly of Wire-gauze and partly of a'metallic plate, in combination with the sieve of a fanning-mill, substantially as described.

2. The separator O, constructed With a flat or arched surface, and having the edge 0 turned up, as described, for the purposevof preventing the grain which is cast upon the separator from falling over that edge.

3. The sieve A and the separator O, in combination with an adjustable dischargingscreen, D, which is shorter than the gains in which it moves, or of the same length, constructed and operating in the manner and for the purpose described.
